Well, I think we need confirmation first that there is an affair going on. The DM does jump to conclusions at times. Perhaps his wife has just got fed up of him.
I tend to agree with Rodo, who knows what is behind the split? Even if PH has left his wife for the new girl, it's more gossip then news isn't it really? I wish the papers would leave people alone - after all he's a TV presenter not a politician, and his personal ethics or lack of them don't affect his job, do they? I do wonder how many of these self-righteous DM journalists lead squeaky clean lives
